CHECKING-I-IINGE.

Specification of Letters Patent.

Patented Sept. 25, 1917.'

Application led May 28, 1914. Serial No. 841,468.

To all whom t may concern:

Be it known that I, EMIL BOMMER, a

citizen of the United States of America, residing in New York, in the borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Checking-Hinges, of which the following is a specification.

This invention relates to improvements in checking-hinges, and has for its object to provide a very simple and efficient form of checking-hinge which acts in the nature of a door-check when used in connection with independent spring-hinges or other doorclosing means, but which is preferably provided with self contained door-closing means, combining the advantage and appearance of a spring-hinge with the utility of a door-check. More particularly the invention consists in the application of two cooperating cam members which move a piston member on the opening or closing of the door, and by which movement of the piston member, a checking-liquid is forced through a regulated and restricted opening of the` piston member, whereby a checking action results.

The invention is shown in the accompanying drawings and will be more fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings,

Figure 1 is a vertical section of my improved spring-hinge provided with my improved checking means applied thereto,

Fig. 2 is a top-view of the embodiment shown in Fig. l,

Fig. 3 is a vertical section of the embodiment shown in Fig. 1, but with the leaves of the hinge arranged parallel and adjacent to each other,

Fig. 4 is a horizontal section taken on line 4-4 of Fig. 3, and

Fig. 5 is a vertical section of another embodiment which is not provided with a spring-hinge structure as the embodiment shown in Figs. 1 and 3. y l

Similar characters of referenceindicate corresponding parts throughout the different figures of the drawings.

Referring to the drawings, and more particularly to Fig. 1, the leaf 10 is provided with ears 11, which are in turn provided with pintle-openings 12 through which the pintles 13 and 14; passi The pintles 13 and 14: are provided at their ends with screwthreaded portions and have their screwthreaded ends 15 and .16 engage screwthreaded sockets of the pintle-heads or tips 17 and 18. The other ends of the pintles 13 and 14 are also screw-threaded and these screw-threaded ends engage screw-threaded sockets of an intermediate member 20, which is secured to the barrel 21 by means of a pin 22. This intermediate member 20 serves as a socket or nut for the pintles 13 and 111, and also servesv as a fixed springholder for the coil-spring 23 of the springhinge portion. This coil-spring has its upper end engaging the end 2-1 of the fixed spring-holder and has its lower end engaging the end 25 of the adjustable springholder 26, this adjustable spring-holder 26 being provided with openings 27 to enable the adjusting of the spring-holder to be readily carried out in the manner well known. A suitable washer 28 is interposed between the barrel 21 and the adjustable spring-holder 26. This spring-hinge portion as described acts like any of the well known spring-hinges, and has the barrel 21 made integral with or secured to the leaf 30. Both leaves 10 and 30 are. provided with suitable openings 10a and 30a for the passage of the screws for fastening the spring-hinge in position.

In the upper part of the barrel 21 is arranged the improved door-checking means, which is perhaps more clearly shown in Fig. 5, to which reference is now made, as the enlarged size of the parts shown in Fig. 5 serves to make clearer the description thereof. As already stated, the embodiment of Fig. 5, however, does not have the springhinge portion which is shown in the embodiments of Figs. 1 to 4. For this reason the member 31 in Fig. 5 acts as a socket or nut for the pintle 32, and is also engaged by a small screw-threaded pintle or rod 33 which engages the member 31, and passes through the ear 34 which is journaled thereon, and has its other end The member 31 is rigidly connected to the barrelv 43, preferably by pins or screws 36. The upper end of the pintle 32 is screwthreaded and engages the tip 37. Adjacent to the upper ear ranged a cam member 40 which has its upper surface 41 parallel with and adjacent to the lower surface of the upper ear 12.,

engage the tip 35.

12 and the leaf 10 is ar-v i 'r e ,closing -the pintle32 and the bore47 of in. `which v60, which has its 7,The cylindrical 'lining and is rigidly connected therewith by screws 46 or other similar fastening means, and is provided with a shoulder 42 in whichv is seated the barrel 43 and which is providedv at its lower-most side or end with a camsurface 44. This cam member 40 is also provided with a vertical channel 45 through whi'chfthe checking-,liquid may be readily inserted and which is closed .bythe screwv 45a, which is preferably provided with al packing 45". A screwdriver may alsobe inserted through this channel 45.toI adjust thescrewjl whenv it is in registration therewith. Thebore 47 of` the cam member has a pintle 32 passingy therethrough and intermediate the. cam member 40 is a sleeve 48, which has its .upper-end seated in the bore 47 and its lower. end terminatingadjacent to a piston member.50. Thispistonmember 150 is provided with an adjustable opening which is acljusted by the checking-liquid regulating. screw-threaded plug 51, andthe piston member150 is alsofprovided with an opening 52.

.afball' 53V is movable. This ballvalve is shown in Fig. 5, and has the ball restingon a support 54 and is adapted to close the opening v55 when the ball is raised from the positionshown in Fig. 5 to its position. From lthe piston 50 eX- tends upwardly a hollow cylindrical portion upper end provided with a camsurface 61, which contacts -with the cam-surface44 of thecam member 40. Be-

; tween the cylindricalfmember and the barrel 43,.the cylindrical lining'member 62,

which extends from the cam member ,40-to the member 31. serves to effect a liquid-tight connection. TheV cam-surfaces 44 and 61 coincide with each other when in one position, 'but when in the other position, `where.

their peaks contact, the greatest amounty of vertical relative movement is attained.

Intermediate the member 3l and the pisr.ton member 50, a coil-spring is arranged, to continually move the 'object of which' is upwardly lthe piston v50 so that the camfs'urface 61 thereof 'will always contact with the' cam-portion 44 of the cam member 40.-

member 62. is provided jn'e'ar itsupperportion withV pins 66. whichfare adaptedtoengageslots 67 Ionthel outer circumferenceof the cylindrical portion 60 of the ,piston 50, in order to prevent arotarymovement of the piston in respect to the pintle.

checking-liquid 'to enter into the space 70' by reason ofthe downward, motion of .the

piston 50, brought about by the coperating cam 'members' 44 and 61.- This will immediately cause the ball 53 to rise and close the opening 55, and anychecking-liquid which will thenflow from the space 7 5 into` the space 70 must. pass through the check,A ing-valve 5l. This, however, is so. regulatedV as to give a certain definite impedance to the flow. of the checking-liquid Hence, asV the cam-surface 61 spect to the cainfsurface 44, the piston member 50 is raised or lowered, and as it is low.- ered, as shown in the position vin Fig. 3. in
